LEMON-SQUEEZER.

SPECIFICATION forming part of Letters Patent No. 576,706, dated February9, 1897.

Application filed May 13, 1896. Serial No. 591,317. (No model.)

To (all whom it may concern..-

Be it known that I, EDWIN WALKER, a citizen of the United States,residing at the city of Erie, in the county of Erie and State ofPennsylvania, have invented certain new and useful Improvements inLemon-Squeezers; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters of reference marked thereon, forming part of this specification.

My invention consists of the improvements in lemon-squeezers hereinafterset forth and explained and illustrated in the accompanying drawings,and embodies such a construction of mechanism that the cup containingthe lemon to be squeezed is rapidly raised into contact with a rotatingcompressor by means of a link until the compressor commences to operate,when a cone or eccentric is brought into operation, which operates moreslowly to compress the lemon and complete the operation.

This invention also embodies a cone-shaped lemon-holder, provided on itsupper surfaces with curved ribs and with perforations for the passage ofthe juice extracted. The curved ribs on this cone start from the centerand curve toward the periphery of the cone in such shape that when therotating compressor acts upon a half lemon placed thereon it tends tocarry the loose pulp and seeds toward the center or apex of the cone,instead of pressing a portion of the pulp out between the peripheries ofthe cone and rotating compressor.

Other features of the invention are hereinafter referred to in thespecification.

In the accompanying drawings, Figure 1 shows a view in elevation of myimproved lemon-squeezer ready to receive the lemon and with theleft-hand side of the frame thereof removed and with the rotarycompressor and the cone-cup and cone-shaped lemon-holder therein insection. Fig. 2 shows aview in elevation of the same, with thecompression cam or eccentric just coming into action and with theright-hand side of the frame and the operating-handle removed. Fig. 3shows a top or plan view of my improved cone for receiving andsupporting the lemon to be squeezed.

In the construction of my invention illustrated in the accompanyingdrawings, A A are the right and left hand halves of the frame, which isprovided with a clamping mechanism B B, by means whereof it can besecured to a suitable support. In the lower part A of the frame areguides a, upon which the part D of the cone-cup D moves up and down. Onone side of the cone-cup Dis an ear (1, in which is secured adownwardly-projecting rod E, to which a glass-holder E isadjustablysecured, the rod E turning loosely in the ear (Z, so that theglass-holder E can be swung sidewise from under the cone-holder D, asdesired.

In the cone-holder D there is a cone-shaped lemon-holder F. (See Fig.3.) This lemonholder is provided on its upper surface with ribs f,curved from the center toward the periphery of the cone in such shapethat when the rotary compressor G (hereinafter described) compresses ahalf lemon thereon the rotation of the compressor G operates to turn thelemon on the cone F, so that the pulp and seeds travel along the curvedribs f toward the center of the cone and thereby prevents any portion ofthe pulp or seeds of the lemon from being pressed out around theperipheries of the cone and compressor. The cone F is also provided withopenings f adjacent to the ribs f for the escape of the juices.

In the upper part of the frame A A there is mounted a transverse shaftH, provided with an operating handle or lever H, and on this shaft II issecured a bevel gear-wheel I, provided with teeth for about four-fifthsof its circumference, which intermesh with a bevel-pinion J on avertical shaft J, to the lower end of which is secured a compressor G,made in the form of a hollow cone adapted to fit down over the cone F.The under surface of the hollow cone Gr is provided with radial ribs g,adapted to engage the lemon to be compressed and rotate it upon the coneF.

In one edge of the wheel I is secured a trans-' verse pin 1', whichprojects out from each side of the wheel I far enough to be engaged byrecesses is in links K, which extend down behind the shaft H and aresecured by means of a pivot c in the part D of the verticallymovingcone-cup D. To the upper end of each of the links K is pivoted a hook L,these hooks on either side being connected together by means of a pin 1,which passes through slots 7; in the ends of the links K, so that thehooks L move up and down in unison. The ends of the pin Z also extendout on each side beyond the faces of the hooks L, so as to engagecam-shaped recesses M m in each side of the frame, so that the upwardmovement of the hooks L is limited thereby. In the edge of the wheel Ithere is also a slot or depression 1 into which the pin Z passes whenthe parts are in the position shown in Fig. 1. On the periphery of thewheel I there is also a cam or eccentric-shaped surface I, whichcommences at or near the point where the pin 1 is located in the wheel Iand extends at a grad ually-increasin g pitch around about one third ofthe periphery of the wheel I and is adapted to engage the central partof the transverse pin Z, through which it acts upon the links K, so asto powerfully compress an ything placed upon the cone F.

In operation, the parts being normally in the position illustrated inFig. 1, the lever H is raised, which operates to rotate the wheel I andcompression-cone G geared thereto, and as the parts move around thepoint illustrated in Fig. 2 the cam or eccentric surface 1 commences toengage the pin Z, raisingthe hooks L, as illustrated in Fi 1. The linksK having meanwhile contacted with the shaft H, the pin 1 passes out ofthe slots is in said links and the cam-surface I continuously operatingon the pin Z forces it upward in the part on of the recess M until thecompression is completed, after which the movement of the lever II isreversed and the parts moved back to their normal position, (illustratedin Fig. 1,) ready for another operation.

Having thus fully described my invention, so as to enable others toconstruct and operate the same, what I claim as new, and desire tosecure by Letters Patent of the United States, is-

1. The combination in a lemon-squeezer, of a rotary compressor anoperating-lever geared to an d rotating said con1pressor,a conecupadapted to be moved up to the compressor, links pivoted to the cone-cup,and hook-andcam mechanism connecting the links with the operatingmechanism, substantially as and for the purpose set forth.

2. The combination in a lemon-squeezer, of a vertical rotatingcompressor a bevel gearwheel geared to and rotating said verticalcompressor, a vertically moving cone cup, links extending from saidcone-cup up on each side of said bevel gear-wheel, a pin in saidgear-wheel adapted to engage said links during a portion of itsrevolution, and a camsurface on said wheel adapted to engage said linksduring another portion of the revolution of said wheel, substantially asand for the' purpose set forth.

3. The combination in a lemon-squcezer, of a conical compressor a bevelgear-wheel geared to and rotating said conical compressor, avertically-moving cone-cup, links pivoted to the frame of said cone-cup,and extending up on each side of said bevel gearwheel, a pin in saidgear-wheel adapted to 011- gage recesses in said links, hooks on saidlinks adapted to keep the recesses in said links in engagement with thepin in said wheel during a portion of the revolution thereof, a pinconnecting said hooks, and a cam on said wheel adapted to engage saidpin and disengage said hooks, and cam-surfaces in the frame engaging theend of said pin, substantially as and for the purpose set forth.

4-. In a lemon'squeezer, acone-shaped support for the lemon to besqueezed, having openings therethrough for the passage of the juices andcurved ribs radiating from the center and extending to its periphery onthe upper SLll face thereof, substantially as and for the purpose setforth.

5. The combination in a lemon-squeezer, of an operating-lever II securedto a shaft II, a bevel gear-wheel I on said shaft, a vertical shaft Jdriven by said gear-wheel, a conical compressor G having ribs 9 on itsunder surface thereof, a vertically-movable conecup D, a cone F havingcurved ribs on its upper surface therein,links K extending from saidcone-cup up on each side of the wheel I, a pin I in said wheel adaptedto engage slots 7a in said links, hooks L adapted to retain said linksin engagement with said pin I during a portion of the revolution of saidwheel, a cam-surface I on said wheel and a pin 7, through the hooks Ladapted to be engaged thereby, and cam-surfaces in the side frame A Aadapted to engage the ends of the pin 7, substantially as and for thepurpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

EDWIN \VALKER.
